Power supply voltage: +5V output frequency F0=F1=2.5K to 200MHz, Matching STM32 program V1 version: F0 is ; F2 and F1 share a PLL and can be configured with a frequency division ratio. STM32 program V2 version: support all functions of V1, external clock input variable Settings, interface 2: F0, F1, F2 shared phase-locked loop, phase related, you can set F1 and F2 and F1 frequency division ratio, at the same frequency can fine-tune the three channel phase relationship, the maximum does not exceed 25°, related to frequency. output interface: SMA female head; The V2 supports external clock input: 10M 15M 20M 25M. configurable minimum step: 1Hz(equipped with STM32+ 1.3-inch TFT)<br><br>size: Length * width =5 x 5CM(excluding the SMA protruding on the right) Height: 2.2CM(including copper column height) Module measurement oscilloscope (Note that for high frequency band, please set the oscilloscope to 50 ohm impedance) Color: As Shown Material: PCB+Metal<br><br>Package Contents: 1 * Signal Generator Module<br><br>Only the above package content, other products are not included.
